* mac80211: handle SMPS action framesJohannes Berg2011-12-191-1/+4
| | | | | | | | | | When a peer changes SMPS state we should update rate control so it doesn't have to detect it by itself. It can't detect "dynamic" mode anyway since that just requires rts-cts handshaking. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| * Bluetooth: Add missing mgmt_confirm_name command definitionJohan Hedberg2011-12-191-0/+10
| | | | | | | | | | | | | | | | | | | | This patch adds the necessary structs for the Confirm Name command. This ensures that the protocol definitions are up to date with the latest mgmt specification. The actual implementation of the command will follow in a later patch-set.

| * Bluetooth: Fix mgmt_(block,unblock)_device opcodesJohan Hedberg2011-12-191-2/+2
| | | | | | | | | | | | | | | | | | | | This patch fixes the opcodes of the Block/Unblock device commands to match with what user-space expects and to confirm with the latest mgmt specification. The reason the values were wrong was a missing Confirm Name command definition (which will be added by a subsequent patch).

| * Bluetooth: Add missing confirm_name field to mgmt_ev_device_foundJohan Hedberg2011-12-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | This patch adds a missing confirm_name field to mgmt_ev_device_found. Support for setting the correct value for this field is not implemented yet, but having it part of the struct definition ensures that user-space gets correct sized device_found events and is thereby able to do at least rudimentary parsing of them.

* | cfg80211: allow following country IE power for custom regdom cardsLuis R. Rodriguez2011-12-161-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By definition WIPHY_FLAG_STRICT_REGULATORY was intended to allow the wiphy to adjust itself to the country IE power information if the card had no regulatory data but we had no way to tell cfg80211 that if the card also had its own custom regulatory domain (these are typically custom world regulatory domains) that we want to follow the country IE's noted values for power for each channel. We add support for this and document it. This is not a critical fix but a performance optimization for cards with custom regulatory domains that associate to an AP with sends out country IEs with a higher EIRP than the one on the custom regulatory domain. In practice the only driver affected right now are the Atheros drivers as they are the only drivers using both WIPHY_FLAG_STRICT_REGULATORY and WIPHY_FLAG_CUSTOM_REGULATORY -- used on cards that have an Atheros world regulatory domain. Cards that have been programmed to follow a country specifically will not follow the country IE power. So although not a stable fix distributions should consider cherry picking this.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The nl80211 station handling code is a bit messy and doesn't do a lot of validation. It seems like this could be an issue for drivers that don't use mac80211 to validate everything.

This would result in the following WARN-ON() along with the failure to notify the user space of the roaming. The other situation which is happening with ath6kl that runs into issue is when the driver reports roam to same AP event where the AP bss entry already got expired. To fix this, move cfg80211_get_bss() from __cfg80211_roamed() to cfg80211_roamed().

Also, this patch adds the HCI_LE_SCAN flag which was created to track if the controller is performing LE scan or not. The flag is set/cleared when the controller starts/stops scanning. This is an initial effort to stop using hdev->flags to define internal flags since it is exported to userspace by an ioctl.
